mirrors monitoring tools

Hi, I've been reviewing 3 solutions suggested for monitoring oVirt's mirror sites: mirmon(used by CentOS), Debian Mirror Checker, MirrorManager(used by Fedora). I've put what I gathered so far here(google docs) <https://docs.google.com/a/redhat.com/document/d/1NErdN07kSLZQ_ystxsp9-6Fw... . imo, there are 2 main problems: 1. monitoring that the mirrors are up and synced( logs and http access) 2. updating the mirrorlist(../yum-repo/mirrorlist) file automatically when a mirror site is not synced after X amount of time. so far installing only mirmon, it seems like the simpler tool that can address problem 1 easily, in order to handle problem 2 another script that filters the log file needs to be written. MirrorManager needs further inspection(has many other features which I am not sure if we need?) and Debian Mirror Checker, i think, is not worth it(incomplete docs, not maintained, debian infra specific - assuming I found the correct repository) what do you think? Thanks, Nadav.
